Answer:
A. f = 8 Hz
B. T = 0.125 s
C. λ = 0.0166 m = 16.6 mm
D. d = 7.98 m
Explanation:
A.
The frequency of the wave can be given as:
[tex]f = \frac{n.\ of\ waves}{time}\\\\f = \frac{360}{45\ s}\\[/tex]
f = 8 Hz
B.
The time period will be:
[tex]T = \frac{1}{f}\\\\T = \frac{1}{8\ Hz}\\[/tex]
T = 0.125 s
C.
The wavelength is given as:
[tex]\lambda = \frac{c}{f}\\\\\lambda = \frac{0.133\ m/s}{8\ Hz}[/tex]
λ = 0.0166 m = 16.6 mm
D.
The distance traveled in 1 minute can be found out as follows:
[tex]c = \frac{d}{t}\\\\d = c\ t\\d = (0.133\ m/s)(60\ s)[/tex]
d = 7.98 m
